Answer:
Atoms or molecules
Explanation:
Because if molecules are heated or colded the can be liquid or solid
From the equation, we see that for every 4 moles of pyrite consumed, 11 moles of oxygen are consumed.
So, the answer is (10.5/4)(11) = <u>28.875 mol</u>
Answer:
89.6 liters
Explanation:
A STP (standard temperature and pressure) ONE mole of any idea gas will occupies 22.4 liters. So,...
4 moles x 22.4 L/mol = 89.6 liters
P1V1=P2V2
100mL•500 mmHg=V2•1000mmHg
50000=V2•1000mmHg
50000/1000mmHg=V2
V2=50mL
Answer:
C. Sodium hydrogen carbonate
Explanation:
IUPAC : International Union of Pure and Applied Chemistry.
According to IUPAC rules:
Baking soda is a salt formed by a cation(Positive charge) and an anion(anion).
: Is made from cation and one anion
IUPAC naming starts from the cation name .(Here the cation name is : Sodium .) The cation is named same as the name of element.
Anion is named after the cation .Here is named as Hydrogen carbonate.(anion name ends with -ate ,-ite -ide etc).
So, name of the compound is Sodium hydrogen carbonate
Note: d.Sodium hydrogen monocarbon trioxide, can't be correct answer, because it show the existence of anions of oxygen()and not )
